Product Details

The ARP 100-1402 is a premium small block header stud kit designed for secure, reliable exhaust header installation. This kit features 3/8" diameter studs with 1.670" length and 12-point nuts with a black oxide finish, providing maximum durability in high-heat, high-vibration environments.

Key Features:

  • Made from heat-treated 8740 chrome moly steel with black oxide finish for corrosion resistance
  • Nominally rated at 170,000 psi tensile strength - far exceeding Grade 8 hardware
  • 12-point nut design allows easy socket access in tight spaces near exhaust pipes
  • Precision-engineered threads ensure proper torque retention and prevent loosening
  • Includes premium-quality washers and 12-point nuts for complete installation
  • Ideal for small block V8 applications requiring secure header mounting

ARP fasteners are engineered to provide complete reliability in severe racing and high-performance environments. The compact 12-point nut configuration is specifically designed to facilitate installation where clearance between the header flange and exhaust pipe is limited. Each kit includes the exact number of studs, nuts, and washers required for your specific application.
